IMPROVEMENT IN MACHINES FOR EMBROIDERING FABRICS.

Specification forming part of Letters Patent 0. 170,596, dated November30, 1875; application filed September 7, 1875.

' To all whom it may concern:

Be it known that I, REUBEN M. ROSE, of Williamsburg, Brooklyn, in thecounty of Kings and State of New York, have invented certain new anduseful Improvements in Machines for Embroidering Fabrics; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawing, which forms part of this specification.

This invention has for its object the production of a machine forembroidering fabrics by means of an interlooped or knitting stitch,which is incorporated with the fabric by passing through the latter.

The invention consists in certain combinations, in anembroidering-machine, of a pointed latch-needle, with a latch-opener anda latchcloser, to insure the proper opening and closing of the latch.Furthermore, the invention consists in a combination, with the pointedlatch-needle, of an intermittingly moving thread-guide, operating toinsure the working of the needle always 'on the proper side of thethread as the latter is drawn from the spool or its equivalent, and toprevent the loop from prematurely slipping off the hook of thelatchneedle.

Figure 1 represents a side view of an embroidering-machine with myinvention applied, and the needle as having commenced its descent.Fig.'2 is a similar view of the same with the parts in position afterthe needle has commenced its ascent. Figs. 3 and 4 are front views, inpart, on a larger scale, with the needle and its accompanying devices inlike positions to those'represented for them in the two former figures,respectively. Figs. 5, 6, and 7 are views in detail mainly of the needleand thread-guide in diiferent positions during the .production of thestitch. Fig. 8 is a plan of the presser-foot detached. Fig. 9 representsa face view of the stitch 011 the upper surface of a piece of fabric.The embroidering-machine represented in the drawing possesses manyfeatures in common with those of different kinds of singlethreadsewing-machines--as, for instance, a cloth-bed or table, a reciprocatingneedle-bar, a presser-foot, and a feeding dog or device.

Ais the reciprocating needle-bar, which may be operated by any suitablemeans to pass the.

the cloth bed or table B. O is the feeding dog or device, which may be afour-motion one,

and be arranged below the table for operation through the latter on theunder surface ofthe fabric, as in various sewing-machines. D is thepresser-foot, which it is preferred to construct with a reduced.portion, 0, on its one side, and oblong slot cl, for thepassage of theneedle through it; but I do not restrict myself to any specialconstruction of said foot. E is a spool-spindle, arrangedbelow thetable, and F an intermittingly-reciprocating threadguide, also arrangedbelow the table and serv iug to conduct and hold the thread e in properrelation, with the needle. G is the pointed latch-needle, carried by thereciprocating needle-bar A. The latch f of this needle is not a merespring, designed to open and close the hook of the needle at specifiedperiods, but is freely pivoted to the body of the needle, and the lattersuitably constructed so. that said latch may either be thrown down toclose the hook g, at the pointed end'of the needle, or be thrown up intoa reverse position, within or against the body of the needle,.and sothat, as the latter passes down through the fabric, the latch is out ofthe way, or in a raised position with its nose or point projectingupward, and L free from all possibility of catching in the fabric.

The operation is as follows: Supposing the needle in its descent to havereached the position represented in Figs. 1 and 3, which is shortlybefore it enters the fabric; then the latch j, which has been left in adownward or closed position against the hook g, is caught at its free orlower end by a latch opener, H, which may be an arm made to project fromthe under side of the head through which the needle-bar plays. The lowerend of this arm or latch-opener lies close up to the needle, and isstepped or otherwise constructed so that the point of the latch, whenthe needle comes down, will be caught by it, and in the further descentof the needle, as represented in Figs. 5 and 6, will be turned or closedupward against or within a hollow, h, of the needle.

To insure this action, and to cause the latch,

when closed, to clear the opener H, during a 2 P I 170.596

the ascent of the needle, said latch-opener or the needle itself shouldbe made elastic relatively to each other.

When the pointed latch-needle G has descended to the position shown inFig. 5, with the latch f raised or open, said latch passes down in frontof a latch-closer, I, which, during such motion of the needle, has noaction upon the latch. The needle Gr, also during its descent below thetable to the position shown in Fig. 5, passes at its pointed and hookedend in front of the thread 0, as the latter is sues from thethread-guide F; but as the needle G continues its descent to theposition represented in Fig. 6, the thread-guide F moves forward andcarries the thread a partly around or across the needle, and remains insuch forward position till the hook g of the needle, in the ascent ofthe latter, has not only fairly got hold of the thread, thus adjustedinto position for the purpose, but so that the loop or thread thuscaught by the hook of the nee-' dle is taken up intothe cloth, or atleast till the latch f has been turned. to close the hook g, so that theloop cannot slip or prematurely leave the hook. After this the threadguide Fretires to its original position to allow the needle, in itssucceeding descent, coming down in front again of the thread e. Prior tosuch return of the thread-guide F however, and when the needle, in itsascent, reaches the positon shown in Fig. 4, the point of the latch fcomes in contact with the forward edge of the inclined back of thelatch-closer I on the under side of the table. This causes the latch tobe turned down and closed over the hook, and so that the latch passes,during the further ascent of the needle with its rear or pivoted end,foremost through the fabric, and the closed hook g of the needle carriesthe loop up through the fabric, and as the needle descend again thelatch f opens and the loop is deposited on the upper surface of thefabric, and held in position by the needle till the latter, in itssucceeding ascent, passes a fresh ,loop through the previous one, afterwhich, and when the needle is out of the fabric, the latter is fedforward, and subsequently the new loop laid on the surface of the fabricfor a repetition of the action, as before.

The latch-closer I, on the under side-of the table, may be constructedin various ways; but making it with an inclined back, as shown, andarranging the needle, so thatlit works close 'up to the face of saidcloser, answers the purpose, the needle having spring, or the latchspringing slightly back when passing V to move the thread-guide Fforward, and a spring, l, to carry it back at the proper timesrelatively with the motion of the needle, as and for the purpose hereindescribed. 1

Although the machine has here been: describedas taking the thread frombelow, it is evident that the needle might be worked from below and.take the thread from above, and the positions of the latch-opener andlatchcloser be correspondingly changed, or theimachine may beconstructed to embroider in various positions other than horizontally. Iclaim- 1. The combinatiomin an embroidering-machine, of the pointedlatch-needle, with the latchopener H and latch-closer I, for catchingand releasing the thread, substantially as described.

2.The combination of the needle Gr, t-0

vided with reversible latch, the latch opener and closer, and thereciprocating thread-guide F, the whole constructed to operatesubstantially as described. f

3. The combination with the reciprocating latch-needle, and latch openerand closer, the reciprocating thread-guide; F, and the feed device 0,the whole constructed and arranged to operate substantially asdescribed.
